Trade API Market-Feed Migration Required by 15 September 2026

The existing Kotak Neo Trade API market-feed WebSocket, also known as the HS feed, will be deprecated on 15 September 2026. After this date, it may no longer deliver market data.

The new market feed uses a different protocol. Changing only the WebSocket URL will not be sufficient—you must update your integration before the deadline.

Here’s what you get with the new feed:

• Lower latency for live ticks
  
• Cleaner and more reliable data
  
• Improved connection stability
  
• Subscription to up to 3,000 tokens in a single request
  
• Multiple feed types, including LTP, touchline, depth, full depth and indices
